If step 6 x, namely y-coordinate pointer DPTR not yet points to last column: DPH < Number_ROW-1, the 2 of jump procedure four), continue to follow the tracks of and add up the lattice point trampled in region, no, then terminate this and follow the tracks of and statistical work；
Step 7, jump to step one, start a new wheel scan detection job；
Described in above-mentioned steps four, the rule of tracing area lattice point includes:
1) tracked region is characterized by: " each coordinate points in tracked region correspond to data #01H, it is necessary to outside tracked region or need the coordinate points between tracked region all to correspond to data #00H "；
2) tracking profile intervalometer is started, if the timing time of this intervalometer is put to predetermined number, reset single-chip microcomputer；
3) data that present co-ordinate position is corresponding are #01H, check the relation of the data corresponding with four, left adjoint point upper, right, lower of present co-ordinate position, determine the moving direction of present co-ordinate position, the path of this moving direction process is formed for the profile in this region, and the rule about mobile present co-ordinate position is as follows:
If a) data that its right adjoint point is corresponding are #01H, the data that it is upper and lower, left adjoint point is corresponding are all #00H, just present co-ordinate position are shifted to its adjoint point place, right；
If b) data that adjoint point is corresponding below are #01H, on it, the data that right, left adjoint point is corresponding be all #00H, just present co-ordinate position is shifted to adjoint point place below；
If c) data that its left adjoint point is corresponding are #01H, on it, the data that right, lower section adjoint point is corresponding be all #00H, just present co-ordinate position is shifted to its adjoint point place, left；
If d) data that above it, adjoint point is corresponding are #01H, it is right, under, data that left adjoint point is corresponding be all #00H, just present co-ordinate position is shifted to adjoint point place above it；
If the data that e) it is right, lower section adjoint point is corresponding are all #01H, the data that it is left, top adjoint point is corresponding are all #00H, just present co-ordinate position are shifted to its adjoint point place, right；
If f) under it, data that left adjoint point is corresponding be all #01H, on it, data that right adjoint point is corresponding be all #00H, just present co-ordinate position is shifted to adjoint point place below；
If the data that g) it is left, top adjoint point is corresponding are all #01H, the data that it is right, lower section adjoint point is corresponding are all #00H, just present co-ordinate position are shifted to its adjoint point place, left；
If h) on it, data that right adjoint point is corresponding be all #01H, under it, data that left adjoint point is corresponding be all #00H, just present co-ordinate position is shifted to adjoint point place above it；
If i) data that its upper and lower adjoint point is corresponding are all #01H, the data that it is right, left adjoint point is corresponding are all #00H, and it is moved by its left adjoint point, just present co-ordinate position is shifted to adjoint point place above it；
If j) data that its upper and lower adjoint point is corresponding are all #01H, the data that it is right, left adjoint point is corresponding are all #00H, and it is moved by its right adjoint point, just present co-ordinate position is shifted to adjoint point place below；
If the data that k) it is right, left adjoint point is corresponding are all #01H, the data that its upper and lower adjoint point is corresponding are all #00H, and it is moved by adjoint point above it, just present co-ordinate position are shifted to its adjoint point place, right；
If the data that l) it is right, left adjoint point is corresponding are all #01H, the data that its upper and lower adjoint point is corresponding are all #00H, and it is moved by adjoint point below, just present co-ordinate position are shifted to its adjoint point place, left；
If m) data that above it, adjoint point is corresponding are #00H, the data that its excess-three adjoint point is corresponding are all #01H, just present co-ordinate position are shifted to its adjoint point place, right；
If n) data that its right adjoint point is corresponding are #00H, the data that its excess-three adjoint point is corresponding are all #01H, just present co-ordinate position are shifted to adjoint point place below；
If o) data that adjoint point is corresponding below are #00H, the data that its excess-three adjoint point is corresponding are all #01H, just present co-ordinate position are shifted to its adjoint point place, left；
If p) data that its left adjoint point is corresponding are #00H, the data that its excess-three adjoint point is corresponding are all #01H, just present co-ordinate position are shifted to adjoint point place above it；
If q) present co-ordinate position is upper, right, lower four data corresponding with four, left adjoint point are all #00H, at this moment, this " unusual corner " is exited in trial: data corresponding for present co-ordinate position are set to #00H, the coordinate figure finally deposited into is taken out from the scratchpad area (SPA) in RAM, giving present co-ordinate position pointer this coordinate figure is (DPH, DPL), namely return to the coordinate place of previous position, then, continue to follow the tracks of next lattice point according to the rule of above-mentioned tracing area lattice point, if able to find next lattice point, continue to the work of tracing area lattice point, otherwise, " the unusual corner " that run into declares tracing area lattice point end-of-job, at this moment, the flag bit of end-of-job is set: F0=1, what detect is trampled the lattice point number Grid=R in region6R5, then, reset R6R5, terminate the work of epicycle tracing area lattice point；
4) move before present co-ordinate position, lattice point enumerator R every time6R5Plus 1；
5) move before present co-ordinate position every time, data rewriting corresponding for present co-ordinate position is become #FFH；
6) in above-mentioned all rules, other data equivalence of described data #00H and non-#01H.
